Today, Queen Letizia visited the QuirónSalud Proton Therapy Center in Madrid which is the first proton therapy facility in Spain.

During her visit, Queen Letizia attended a meeting presenting the Center before touring the new facility. Proton therapy is an “external radiotherapy treatment which represents an advanced, safe and effective alternative in the fight against some types of cancer.”

Queen Letizia wore a new Massimo Dutti dress (with thanks to @letizia_de_princesa_a_reina) with her Carolina Herrera pumps, her gold hoop earrings, and her Karen Hallam ring.
